I call the external method like this from DTML... set_owner(restrictedTraverse(path_to_user)), where path to user is a physical path, but I'm using the ZUserFolder, so I can use the restrictedTraverse to get to users. UserFolder has a different API. You could do this if your acl_users is a standard UserFolder... set_owner(acl_users.getUser(user_name)) in DTML or make your external method this... def set_owner(self, user_name): self.changeOwnership(self.acl_users.getUser(user_name)) OK, so that should keep you busy for a while. Anyway, the point is that the parameter to changeOwnership is a User _object_. Good luck. --Tim -----Original Message----- From: Magnus Heino (Rivermen) [mailto:magnus.heino@rivermen.se] Sent: Thursday, May 10, 2001 7:25 AM To: 'Tim McLaughlin'; 'zope-dev@zope.org'; Magnus Heino (Rivermen) Subject: SV: Subject: [Zope-dev] change ownership I can get it to work :-/ I get an attributeerror on aq_inner in lib/python/AccessControl/Owned.py, line 302, in ownerInfo Seems as if the user i provide isn't of the right type? How do you use your method? How is it being called? /Magnus

Magnus, No, changeOwnership is not exposed for TTW calling. But you can expose it through an external method... I used this one on a ZClass.

def set_owner(self, user): self.changeOwnership(user) return
